Proof step 4 from proof lebs-in-ri-in-gstore-explicit (previous step)

ri[key] = @(m, m0, m1), key ∈ ri, ri.lebs ⊆ dom gstore ⊦ m ∈ gstore

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ ns ⊆ ns0 ↔ (∀ n. n ∈ ns → n ∈ ns0)
Proof step 6:
ri[key] = @(m, m0, m1), key ∈ ri, ∀ n. n ∈ ri.lebs → n ∈ dom gstore ⊦ m ∈ gstore

Rule argument

spec: set-basic, inst: nat-set name: Subset seq: ⊦ ns ⊆ ns0 ↔ (∀ n. n ∈ ns → n ∈ ns0) subst: [ns0, ns] → [dom gstore, ri.lebs] flags: <all paths>

Additional information

Used terms: dom gstore, ri.lebs
